Application

Diphenylamine can undergo palladium-catalyzed intramolecular cyclization to form carbazole. It may also be used as a starting material in the synthesis of triphenylamine.
Diphenylamine may be used in the preparation of diphenylamine reagent, which is employed for the quantitative estimation of nucleic acid (DNA) from various biological sources by colorimetric method.
